I just checked their website and found another study of trained
cyclists
that showed a 15.6% increase in VO2max and an 11.6% icrease in max
power.

Luttrell and Potteiger found no difference in VO2Max.


That group trained for 3 hours per week at 70% of VO2Max for 6 weeks
versus 8 hours per week (20% anaerobic) for 6 weeks. The second test was
considerably more extensive. There was also no control group for the
second test. What does it take to get an appropriate and properly
designed test?
Max sums it up well.......Dr. Testa was quick to indicate that a fully
controlled study is still needed, but that preliminary impressions from
several high caliber athlete's had been very positive. With riders like
Danielle Nardello and Stefano Garzelli liking the results and producing
more even power output from using them. He had also seen some 25 - 30
watt gains at LT (lactate threshold) in people using them for the first
time, but also said that other training stimulus were present. He calls
them a "very valuable tool" and something that forces everyone, pro's
and amateurs alike, to be more efficient by forcing you to carry the
weight of the up stroke leg and also maintain force through the entire
range of motion. "It's something that nothing else forces you to do and
it makes you do work that is without a doubt of benefit.""
